A really basic and cheap nokia with a black and white screen and a torch (which has come in handy many times, I say torches for all!!)... my last phone was nicer but alas it fell in a toilet and drowned ()
iphone 4s. Got it only a few months back, way after everyone else had already owned iphones. love it so far, compared to my previous which was nokia. I used to swear by nokia but they disappoint in this era of smartphones.
I have a Samsung Galaxy Ace and it's really good... except if you're not careful, you'll run into things that send adverts to your phone 24/7, and also things that slow down your phone so that you have to restart it again. It can be pretty annoying.
